strip quotation marks as workaround for pytest option parsing

[zacharyburnett]

This PR addresses an issue where the regression tests fail to parse results, due to what appears to be an issue where the option parser adds quotation marks to the value:

I find it interesting that another recent run in JWST-Developers-Pull-Requests didn't seem to have this problem. At least the status indicator came back green. https://plwishmaster.stsci.edu:8081/job/RT/job/JWST-Developers-Pull-Requests/1107
So what's different about the setup over there?

This run had lots of unrelated failures and errors, because it was run against CRDS_OPS, which is missing at least one new reference file needed by the latest cal code. It needs CRDS_TEST. Should run using "CRDS_PATH=/grp/crds/jwst/test" in the ENV_VARS.
